POWDER DISPENSER.

Application filed December 26, 1919. Serial o. 347,382.

To all w 710m t 'may concern Be 'it known that I, F RANK MCLAUGHLIN, a citizen of the United States ofmerica, and resident of Ottawa, in the Province of Ontario, Dominion of Canada, have invented certain new and useful improvements in Powder Dispensers, of which the following is a specification.

rlhis invention relates to dispensers, designed for use with powdered soap, toilet powders, medicinal powders, and powders generally, and the objects of the invention are to facilitate dispensing a quantity of powder adequate for the required purpose, to render the dispenser water and moisture proof, airtight and germ proof under all conditions, and other objects which will be made clear hereafter.

ln the accompanying drawings, an embodiment of my invention is illustrated with reference to a lather brush, but it should be understood that l do not limit myself to such an arrangement, which is only illustrative of one application of the invention.

ln the drawings.

Figure 1 is an elevation of an embodiment of my invention.

Figure 2y is a longitudinal section of the device shown in Figure 1.

Figure 3 is a transverse section through the dispensing device shown in Figure 2.

Figure et is a fragmentary longitudinal section of a dispenser showing an alternative method of ejecting the powder. p

Figure 5 is a fragmentary enlarged vertical section of a lateral wall of a dispenser showing the dispensing mechanism in outward position.

Figure 6 is a vertical section through the cover or cap of the dispenser.

Like characters of reference refer to like parts in the several figures.

Referring to the drawings, A represents a powder dispenser, which in the embodiment illustrated is utilized in conjunction with a' lather brush B, but the dispenser may be used individually, and its use is largely governed by the nature of the powder being dispensed.

rlhe dispenser A comprises a casing 10, having a lower closed conical end 11, which is engaged with the lather brush B, and the opposite end of the casing is closed by a cover or cap 12, which frictionally fits the end of the casing and is provided with a end of the conduit, on which the greatest forces are exerted. n

In alignment with the conduit 17, is a cylinder 19X having an outer flanged endl 20, which engages the lateral wall of the casing, and gives a proper support to the innerk end of the cylinder, which is provided with a plurality of peripheral apertures or slots 21.

A rod 22 is slidably mounted yin. the cylinder 19", and conduit 17, and theend of the rod adjacent to the conduit is formed withl a closing member 23, which frictionally engages the inner wall of the conduit, andthe opposite end of the rod is formedl with an yendiof the casing enlarged finger orl thumb .press 24, which f slidably engages the cylinder 19X.

The member 23 is normallyclosed by a spring 25, which encircles the rod 22,and is located between the inner end of the cylinder 19 and the finger or thumb press 24.

The rod 22 carries an ej ecting compressing l .y

and retaining member 26, which is spaced from the closing vmember 23, and consists of a plate or disc having a peripheral flange 27 forming a dished head.

When the casing' 10 is to be lled with"` soap powder, the user grips the casing 10 in one hand, and the cover or'cap 12 in the other hand, and applies a pull longitudinally to the cover,'whereupon the projections 14.

of the resilient arms 13 are disengaged from the recesses 15, allowing thecover or cap 12" to be removed, leaving the upper end of the casing open for filling purposes.

0n replacing the cover or cap 12, the projections` 14 on the resilient arms 13 re-engage the recesses 15, so holding the cap in position. x

Some of the powder in the lower end of the casing 10 will lill the conduit 1,7, and will also collect between the closing member 23 and the member 26, and on moving the rod CJI 22 longitudinally under thumb pressure applied to the thumb press 24, the soap powder held between the closing member and ejector will be dispensed through the conduit, the ejector cutting off any excess or' powder irom the casing, so that only a predetermined quantity of powder will be discharged through the conduit.

The conduit 17 acts as a stationary measuring device.

After dispensing this powder the thumb pressure is released from the thumb press 24C, and the rod 22 is retracted by the spring 25, so that'the closing member closes the conduit 17.

This dispensing operation is repeated each time it is desired to dispense powder, and if soap powder is being dispensed it is dis charged into a shaving cup, and lathered in the ordinary manner.

Referring now to Figures l and 5, the casing l() is provided with a conical valve seat 28, with which the closing valve 29 mounted on the rod 22 engages, and the outer race of the valve 29 is rounded, to drain olf any water which runs from the brush B down on to the casing, so that no water can enter the casing and mix with the soap.

The ejector 30 is the Yfacsimile of that previously described, but it is so arranged that it will embrace the inner end of the conical valve seat 28, as shown in Figure 5, during the dispensing of powder.

The cylinder 19, finger press 24, and spring Y 25 is the same as described above, and need not be enlarged on.

When using a dispenser of this type, the powder is retained between the valve 29, and the ejector 30, and when the rod 22 is moved longitudinally under thumb pressure, then the powder between the valve seat 28 and the ejector 30 is compressed and discharged.

The ejector 30 embraces the inner end of the valve seat 28, and cuts off the supply of soap from the casing, so that only a predetermined quantity of soap is discharged on the actuation or' the rod 22.

The valve 29 lis returned to its normal position by the spring 25, when the thumb pressure is removed from the member 24.

After each dispensing operation, the powder collects ,around the rod 22 lbetween the ejector and the valve, and will be dispensed during the subsequent operation or' the said rod.

The object of forming apertures or slots 21 in the cylinder 19 is to allow any powder which may ,collect in the cylinder being returned into the casing l0 during` the outward movement of the rod 22, and thus the powder cannot impair the action of the spring 25 by clogging therearound.

rlhe brush B is held by resilient means on the casing 10, and comprises a cap portion 35, one portion oit which is formed conical as shown at 3G to engage with the conical end 11 oit the casing l0, and a plurality oi: resilient lingers Il? are provided, having proj ections 38 inthe end which engage with depressions in the outer wall oit the casing 10.

The cap portion 35 is Jformed with a conical end39, which is separated from the conical portion 36 by 'the wall llt), which is provided with a j'ieripheral flange rolled into positionto engage the annular recess 4l provided at the junction of the conical portions 39 and 36 respectively.

The bristles or the brush B are set in rubber in the conical portion 39,.

llfhen removing` this brush, the outer face oi' the wall of the annular recess 41 provides a linger grip, which is gripped by one hand of the user, and 'the casing 10 is gripped by the other hand, and when a longitudinal pull is applied to the brush, it will be bodily removed from the casingn lt should be noticed that in replacing a brush the conical portion 1l of the casing 10 acts as a guide for the resilient fingers 37 and assists in spreading the same.

The conduit 1"? and cylinder l?) are so arranged that water flowing down 'from the brush on the outside oi1 the casing cannot enter and mix with the soap.

As many changes could be made in the above construction, and many apparently widely dii'lerent embodiments ot my invention, wit-hin the scope ot the claim, constructed without departing Yfrom. the spirit or scope thereof, it is intended that all matter contained in the accompanying speciiication and drawings shall be interpreted as l illustrative and not in a limiting sense.

`What l claim as my invention is A dispenser for material in'` powdered form comprising a powder containing casing having a laterally directed powder discharge orifice in its wall, an annular flange surrounding such orifice, a spring held plunger rod having a head having its exterior diameter corresponding in diameter to the interior diameter of the annular iiange and provided with a narrow annular edge portion itting within and around the interior periphery of the flange, manual means for operating the plunger rod to carry the head outward clear of the rlange and means 'following up the head during its outward movement and enytering the annular iange ttor ejecting the powder interposed between such head and the ejecting means when the head is clear of the flange.
